If I keep digging underground, will I dig the earth? (Ideally)

I suggest reading Liu Cixin's "The Earth Cannon", which contains a discussion on this issue.

It is quoted from Liu Cixin's "The Earth Cannon" .......................................................................................................................................................... I don't know whether it is intentional or unintentional, but this question is actually very expert. The key technology of fission nuclear bomb is centripetal compression. When the nuclear bomb is detonated, the fission material is compressed into a compact sphere by the explosive force of conventional explosives wrapped around it, reaching the critical density and triggering a severe chain reaction, resulting in a nuclear explosion. All this will happen in one millionth of a second, and the centripetal compression of fissile material must be extremely accurate. Even the smallest imbalance of centripetal pressure may blow up the fissile material before it reaches the critical density. In that case, what happens is just an ordinary chemical explosion. Since the birth of nuclear weapons, researchers have designed various shapes of compressed explosives with complex mathematical models. In recent years, they have tried to get accurate centripetal compression by various means with the latest technology. "Sugar coating" is one of such technical ideas.

"sugar coating" is a kind of nano-material. When making fission bombs, people wrap nuclear explosives with "sugar coating", and then wrap a layer of conventional explosives outside the "sugar coating". "Sugar coating" has the function of automatically balancing and distributing the surrounding compressive stress. Even if the compressive stress generated by the explosion of the outer explosive is uneven, the nuclear explosive wrapped by it can still be accurately compressed centripetally through the stress balanced distribution of "sugar coating".

Shen Huabei said: "The white sphere you see surrounded by eight nuclear warheads is an alloy material wrapped in sugar coating, which will be subjected to great centripetal pressure in the nuclear explosion. This is a study that we plan to carry out during the whole destruction process. After all, this is a rare opportunity: when all the nuclear bombs disappear, it is difficult to produce such a large instantaneous compressive stress on the earth in a short period of time. It will be very interesting to test what the materials will become and what will happen under such great centripetal pressure. We hope that through this research, we can find a bright future for the' sugar coating' technology in the civil field. "

A UN official said, "You should put the graphite in a' sugar coating' so that we can get a large diamond every time we explode, and the costly nuclear destruction project may become profitable."

A few laughs are heard in headphones, and officials with no technical background are always despised on this occasion. "The pressure generated by the 8,-ton nuclear explosion is many orders of magnitude greater than the pressure to convert graphite into diamond." Some people say.

Shen Yuan's bright children's voice suddenly sounded in everyone's headphones: "Of course, the big bang didn't produce diamonds. Let me tell you what it was: it was a black hole! A little black hole! It will suck us all in and suck the whole earth in! Through it, we will drill into a more beautiful universe! "

"Hehe, son, the pressure of this nuclear explosion is too small ... Dr. Shen, your son's small head is really unusual!" Kevinsky said, "What about the test results? What did that alloy become? I think you probably can't find it? "

"I don't know yet. Let's go and have a look." Shen Huabei pointed forward and said. The nuclear explosion made this huge hole in a regular spherical shape, so the bottom of the hole was a small basin. In the middle of the distant basin, several headlights shook. "That's the people from the sugar-coated experimental project team."

everyone walked towards the center of the basin, feeling like walking down a long hillside. At this moment, Kevinsky suddenly stopped, then squatted down and put his hands on the ground. "There is vibration underground!" "

others felt it, too. "It's not an earthquake caused by a nuclear explosion, is it?"

Zhao Wenjia shook his head: "The geological structure in the area where the destruction site is located has been repeatedly surveyed, and it will never induce an earthquake. This vibration is not an earthquake. It appeared after the explosion and continues until now. Dr. Deng Yiwen said that it is related to the' sugar-coated' experiment, and I don't know the details."

As they approached the center of the basin, the vibration coming from the depths of the stratum gradually increased, until the soles of the feet were numb, as if there was a rough giant wheel spinning wildly in the depths of the earth. When they came to the center of the basin, one of the small group stood up. He was Deng Yiwen mentioned by Zhao Wenjia just now, the head of the material nuclear explosion compression test project.

"What's that in your hand?" Shen Huabei pointed to a mass of white things in Deng Yiwen's hand and asked.

"fishing line." Dr. Deng said, and the group of people squatting on the ground in a circle were staring at a small hole in the ground. The hole appeared on the surface of the melted and condensed rock, with a diameter of about 1 cm and a very regular circle. The edge was very smooth, like a hole drilled by a drill. Zheng Yiwen's fishing line was continuously lowered into the hole. "Look, it has been put for more than 1, meters, and it is far from the bottom. After radar detection, this hole is more than 3, meters deep and is still extending. " "How did it come from?" Someone asked. "The compressed test alloy was drilled out, and it sank into the stratum, just like a stone sinking on the sea surface. This vibration was transmitted when it passed through the dense stratum."

"oh, my god, this is a miracle!" Kevinsky exclaimed, "I thought that alloy would just be evaporated by the high temperature of nuclear explosion." Deng Yiwen said: "If there is no sugar coating, it will be like that, but this time it will be compressed into a new material form by the centripetal pressure gathered by the sugar coating before it can be evaporated. It is more appropriate to call it supersolid, but we already have this name in physics, so let's call it new solid."

"You mean, the specific gravity of this thing is compared with the specific gravity of formation rocks, just as the specific gravity of stones is compared with water?" "It's much bigger than that. The main reason why stones sink in water is not the proportion, but because water is liquid-the proportion of water does not change much after freezing, but the stones placed on it will not sink. Now the new solid matter actually sinks in the solid rock, which shows how amazing its density is! "

"You mean it became neutron star matter?"

Deng Yiwen shook his head: "We haven't measured it accurately yet, but we can be sure that its density is much smaller than the degenerate matter of neutron stars, which can be seen from its sinking speed. If it is really a neutron star material, it will sink in the stratum like a meteorite falling into the atmosphere, which will cause volcanic eruptions and major earthquakes. It is a material form between ordinary solid state and degenerate state. "

"will it sink to the center of the earth?" Shen Yuan asked.

"Maybe, son, because after sinking to a certain depth, the stratum material will become liquid, which will be more conducive to its sinking!"

.................

People with rich imagination are often helpless in the cold. On the contrary, those who are strong in reality and grasp the historical trend have only a brain with poor imagination. Your son, on the other hand, is one of the few people in history who combined the two. Most of the time, reality is just a small island in his fantasy ocean, but if he wants, he may turn his world over at any time, making fantasy an island and reality an ocean. He is the best sailor in both oceans ... ""I know my son, so you don't have to waste time on it. " Shen Huabei interrupted Deng Yang.

"But in any case, you wouldn't think how high Shen Yuan climbed in reality and how much power he had, which enabled him to turn his most abnormal fantasies into reality. Unfortunately, society did not find this danger early. There may have been people like him in history, but they all disappeared into the vast space like asteroids that grazed the earth without releasing their energy in this world. Unfortunately, History has given your son a chance to create disaster with abnormal fantasies.

"In the fifth year after you entered hibernation, the world's competition for the Antarctic continent has a preliminary result: this continent has been identified as an area of global development, but all major countries have won a large area of exclusive economic zones for themselves. It is the only hope for major countries to get rid of the economic recession caused by environmental problems and resource depletion to make themselves prosperous in the economic zone of the Antarctic continent as soon as possible, and' the future is on top of the earth' became a well-known slogan at that time. " Just then, your son put forward that crazy idea, claiming that the realization of this idea would turn the Antarctic continent into the courtyard of this country, and it would be more convenient to go to the South Pole from Beijing than from Beijing to Tianjin. This is not a metaphor, but it is true that the travel time is shorter than that to Tianjin, and the energy consumption and pollution are less than that to Tianjin. At the beginning of that famous TV speech, the audience all over the country laughed as if watching a farce, but they soon quieted down because they found that the idea really worked! This is the idea of Antarctic courtyard, and then a disastrous Antarctic courtyard project was started according to it. "

At this point, Deng Yang was inexplicably silent.

"Go on, what is the idea of an Antarctic courtyard?" Shen Huabei urged.

"you will know." Deng Yang said coldly.

"Then you can at least tell me what I have to do with all this?"

"Because you are Shen Yuan's father, isn't it very simple?"

"bloodline theory is popular now?"

"Of course not, but your son's numerous confessions make the bloodline theory suitable for you. When he became world-famous, he sincerely claimed that most of his thoughts and personality were formed from his father before he was eight years old, and the years after that were just a supplement to some knowledge details. He also stated that the original creator of the Antarctic courtyard idea was also his father. "

"what? ! Me? Antarctic ... Courtyard? ! This is simply ... "

" Listen to my last point: you also provided the technical foundation for the Antarctic courtyard project. "

"What do you mean? ！”

"Of course, it's a new solid material. Without it, the idea of an Antarctic courtyard is just a dream, and with it, this abnormal fantasy immediately becomes a reality."

Shen Huabei shook his head in confusion. He really couldn't imagine how the ultra-high density new solid material could turn the Antarctic continent into the courtyard of this country.

at this moment, the car stopped.

= = = = = = = = = = = = = = = = = = = = = = = 4. After getting off at the Gate of Hell, Shen Huabei saw a strange hill head on. The mountain was a single rust color, and there was no grass in sight. Deng Yang tilted his head to the hill and said, "This is an iron mountain." Seeing Shen Huabei's surprised eyes, he added, "It's just a big piece of iron." Shen Huabei looked around and found that there were several such iron mountains nearby, which stood abruptly on this vast plain with strange colors, giving it an exotic scenery.

Shen Huabei is now able to walk, and he hobbles with the gang to a tall building in the distance. The building is a perfect cylinder, hundreds of meters high, with a smooth surface and no openings. As they approached, they saw a heavy iron gate sliding away to one side, revealing an entrance. A group of people walked in and the door closed tightly behind them.

In the dim light, Shen Huabei saw that they were in a place like a sealed cabin. On the smooth white wall, there was a long row of sealed suits like spacesuits. People took a set of sealed suits from the wall and put them on. With the help of two people, he began to put on one of them. In the process, he looked around and saw a closed sealed door opposite. There was a red light on the door, and there was a luminous digital display next to the red light. He saw that the atmospheric pressure was displayed. When his heavy helmet was tightened, a transparent liquid crystal display area appeared in the upper right corner of the mask, showing rapidly changing numbers and graphics. He only saw that it was the self-inspection of each system inside the suit. Then, he heard a low hum outside, as if something was started, and then noticed that the atmospheric pressure displayed above the opposite door was rapidly decreasing, and it was reduced to zero after about three minutes. The red light next to it turned into a green light, and the door opened, revealing the dark inside of the sealed building.

Shen Huabei confirmed his guess: this is a transition cabin from atmospheric area to vacuum area, so the interior of this huge cylinder is vacuum.

A group of people walked into the entrance, and the door closed at the back. They were in the thick darkness. Some people turned on the lights on their helmets, and several light beams appeared in the darkness, but they could not shine far. A familiar feeling appeared, and Shen Huabei couldn't help shivering, and there was an inexplicable fear in his heart.

"Go ahead." Deng Yang's voice rang out from his headphones. The halo of the headlight reflected a small bridge in the front, less than one meter wide, and the other end reached into the darkness, so I couldn't see how long it was, and the bridge was dark. Shen Huabei stepped onto the small bridge with trembling legs, and his heavy boots made a hollow sound on the thin iron plate bridge deck. He stepped out of a few meters and turned around to see if the people behind him had caught up. At this time, everyone's headlights went out at the same time, and the darkness swallowed everything up. But it only lasted for a few seconds, and blue light suddenly appeared under the bridge. Shen Huabei looked back, only he got on the bridge, and everyone else crowded around the bridge and looked at him. In the blue light from the bottom up, they looked like a group of ghosts. He looked down on the railing by the bridge, and the fear of blood coagulation almost seized him.

he is standing on a deep well.

the diameter of this well is about ten meters, and there is a circular aperture on the shaft wall at regular intervals, which indicates the existence of a deep well in the dark. He is standing in the middle of the small bridge across the wellhead. From here, the well is bottomless, and countless apertures on the borehole wall gradually shrink until it becomes a little bit. He seems to be overlooking a big target with blue light.

"Start the trial now, and pay back everything your son owes!" Deng Yang said loudly, and then turned a wheel installed at the bridgehead with his hand, muttering, "For my abused youth and talent ..." The bridge tilted at an angle, and Shen Huabei grabbed the railing on the other side and tried to make himself stand firm.

Then Deng Yang gave the wheel to the orphans left by the central fracture disaster, who also turned it hard: "For my melted parents ..." The inclination angle of the bridge increased a little.

The wheel was passed to the orphan girl left by the bolt loss disaster. The girl glared at Shen Huabei and turned the wheel hard: "For my evaporated mom and dad ..."

The attempted suicide grabbed the wheel from the orphan girl left by the bolt loss disaster: "For my money, my Rolls Royce and Lincoln, my seaside villa and swimming pool, for my ruined life, and for my wife and children who lined up for relief in the cold street.

The schizophrenic who lost all his wealth also rushed to turn the wheel with the attempted suicide because of losing all his wealth. Obviously, his illness is still not good, so he didn't say anything, just facing down.
